Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper presents an exactly solvable integrable statistical model for fluid systems that links finite-size virial expansions to nonlinear hydrodynamic PDEs, demonstrating how thermodynamic phase transitions emerge as shock waves in the infinite-particle limit and applying this framework to map the QCD phase diagram while quantifying how finite-size effects obscure critical signatures.
This paper proposes using the one-point energy correlator (OPEC) in transversely polarized proton-proton collisions as a novel, infrared-and-collinear safe method to probe the nucleon's transversity distribution with a clean angular asymmetry over a wider kinematic range than traditional hadron transverse momentum measurements.
This paper analytically demonstrates that the variation of the quark-gluon plasma volume in ultracentral collisions depends on initial density fluctuations and is negligible when total entropy scales with the mass number, thereby establishing that measurements of average transverse momentum can probe detailed nuclear structure and pre-equilibrium dynamics.
This paper proposes that quantum entanglement serves as a unifying foundation for statistical and high-energy physics, arguing that systems naturally evolve toward a Maximal Entanglement Limit where thermalization and probabilistic behaviors emerge from the geometry of high-dimensional Hilbert spaces without requiring ergodicity or classical randomness.
This paper demonstrates the feasibility of incorporating Fermi-Dirac statistics into boost-invariant perfect spin hydrodynamics simulations for spin-1/2 particles, revealing that while the resulting corrections are an order of magnitude smaller than spin feedback effects, the approach requires careful handling as numerical solutions can break down under extreme spin polarization.
This paper challenges the recent MAMI collaboration's determination of the hypertriton binding energy by proposing that the observed sharp pion-momentum line instead originates from the weak decay of the ground state of hyperhelium-7 into lithium-7.
This paper presents precise mass measurements of neutron-deficient Cd isotopes using ISOLTRAP at CERN to determine the shell gap at and constrain the mass surface near Sn, revealing an enhancement of the shell gap towards the doubly magic nucleus that challenges state-of-the-art theoretical models.
This paper investigates how neutron decays into dark baryons affect bulk viscosity in neutron star mergers, finding that while the standard slow decay rate only slightly reduces viscosity, a faster decay rate could significantly enhance it and rapidly dampen merger oscillations.
This paper extends a previously developed generally covariant formalism to incorporate the diffusion of conserved charges, while clarifying the apparent distinction between chemical potential and diffusion terms.
This paper introduces Systematic Analytic Regularization (SAR), a novel scheme that regularizes quantum field theories by analytically continuing the power of the kinetic operator at the action level to ensure formal finiteness, and demonstrates its self-consistent application to and Yukawa theories at next-to-leading order.
